P2463 — DPF: excessive soot accumulation

Severity: Serious Can you drive? With caution: limp mode possible, have it checked soon Make: All makes (OBD-II standard)
MeaningEstimated soot load in the filter has passed the limit. This code appears when regeneration cycles failed to complete and the ECU decides to protect the engine.
FamilyPowertrain (P)

Typical symptoms

Reduced power
DPF light on
Regeneration restarting constantly
Rough idle during regeneration

Common causes

Interrupted regenerations
Leaks in the intake circuit
Leaking injectors producing more soot
Exhaust gas temperature sensor out of calibration

What to do

A diagnostic regeneration is needed and, above all, an answer to why the automatic ones never finished: unless the cause is corrected (driving pattern, EGR, injection), the code returns within a few hundred kilometres.
